If you’ve ever thought “we should really have an emergency kit” and then closed the tab because it felt like too much — you’re not alone, and you’re not behind. A 72-hour emergency kit isn’t about preparing for the end of the world. It’s about making sure that if the power goes out for a weekend, a storm closes the roads, or you need to leave home in a hurry, your family has what it needs for three days without scrambling.
Three days is the standard because it’s roughly how long emergency services need to reach everyone in a widespread disruption — after that, help and supplies are generally reaching people. So a 72-hour kit isn’t a bunker. It’s a well-thought-out bag or bin that covers the basics until things stabilize.
This checklist is written for real homes — including apartments, where a garage full of supplies simply isn’t an option. Everything here fits in a closet, under a bed, or in a couple of stackable bins.
Start With the Non-Negotiables
These four categories cover the majority of what actually matters in the first 72 hours of a disruption. If you build nothing else, build these.
1. Water
Plan for one gallon (about 4 liters) per person per day — that’s roughly 12 liters per person for three days, split between drinking and basic hygiene. For an apartment, that’s easiest to manage with:
- A few large, stackable water containers (5–10L collapsible jugs are apartment-friendly and
store flat when empty)
- A basic water purification method as backup — purification tablets or a small filter straw,
in case you need to stretch your supply
2. Food
Three days of food that needs little or no preparation:
- Shelf-stable items you’d actually eat — crackers, nut butter, dried fruit, canned goods with
ring-pull lids, granola or energy bars
- A manual can opener (don’t assume you’ll have one on hand)
- A note in your calendar to check expiry dates twice a year
3. Light and Power
- A flashlight or headlamp per person, plus spare batteries stored separately (batteries left
inside a flashlight can corrode over time)
- A small battery or hand-crank radio, ideally one that can also charge a phone
- A basic power bank, charged and rotated every few months
4. First Aid and Medication
- A compact first aid kit — plasters, gauze, antiseptic wipes, pain relievers, tweezers,
scissors
- A written list of any prescription medications and dosages for each family member
- A small backup supply of essential medication where your doctor allows it
The Second Layer: Comfort and Practicality
Once the essentials are covered, these items are what make 72 hours manageable instead of just survivable.
- Cash in small bills — card readers and ATMs may not work without power
- Copies of important documents — ID, insurance, lease or deed, in a waterproof pouch
- A change of warm clothing and sturdy shoes per person
- Basic hygiene items — toothbrush, soap, wet wipes, sanitary products
- A whistle — for signaling if you need to be located
- Something for morale — a deck of cards, a book, a small comfort item for kids; the goal is
calm, not just survival
If you have pets, add a few days of their food, any medication, and a way to secure them (a leash or a carrier that lives with the rest of the kit, not in a separate cupboard you’d forget under stress).
Where to Actually Keep It (Especially in an Apartment)
The most common reason a 72-hour kit doesn’t get built is that it feels like it needs its own room. It doesn’t. A few apartment-friendly options:
- Under-bed storage bins — flat, out of the way, easy to grab
- The back of a coat closet — a stackable bin or two, with the heaviest items (water) on the
bottom
- A single grab-and-go duffel bag near the door, packed with the lightest, most essential
items, if you might need to leave quickly rather than shelter in place
Whatever you choose, keep everything in one or two locations that every adult in the household knows — not spread across drawers where half of it gets forgotten in an actual emergency.
Build It in Stages, Not All at Once
You don’t need to buy everything this weekend. A realistic approach:
- This week: water and a first aid kit
- Next payday: food and a flashlight/radio
- Within the month: documents, cash, and the comfort items
Building gradually also means you’re less likely to over-buy items you won’t actually use — pick things your household would genuinely reach for, not just what a checklist says.
If you’d rather work from a printed, done-for-you version of this checklist while you shop, the free 72-Hour Family Guide walks through the same staged approach in a printable format you can stick on the fridge — no need to keep re-reading this page while you build.
Keep It Alive
An emergency kit built once and never touched again slowly becomes useless — food expires, batteries corrode, kids outgrow the spare clothes. Put a reminder in your calendar twice a year (spring and autumn work well) to open the kit, check dates, and swap anything that’s changed.
This is exactly the kind of ongoing task that’s easy to plan for once and forget — which is why having a simple, repeatable system (what’s in the kit, when it was last checked, what needs replacing) makes the difference between a kit that’s actually ready and one that just feels ready.
FAQ
Do I really need 72 hours of supplies if help usually comes faster than that? Often, yes — but “usually” isn’t guaranteed, and 72 hours is a reasonable, widely-used planning window rather than a worst-case one. Even a partial kit is far better than none.
What if I live in a small apartment with no storage space at all? Start with the smallest version: one grab-and-go bag per household, prioritizing water, a flashlight, first aid, and documents. You can expand from there as space allows.
Do I need different supplies for a power outage versus needing to evacuate? The core kit covers both. For an outage, you’ll mostly stay put and use it at home. For an evacuation, the same kit — plus the grab-and-go bag if you have one — travels with you.
How much does a full kit cost to build? Spread across the staged approach above, most households can build a solid kit for a modest grocery-budget cost over a month, especially by starting with items already at home (spare batteries, an old backpack, extra canned goods) rather than buying everything new.
Is this actually enough, or should I be doing more? For most households, a well-maintained 72-hour kit covers the realistic scenarios you’re likely to face — a power cut, a storm, a short-notice evacuation. It’s a calm, practical baseline, not a ceiling; add to it over time if it gives you peace of mind.
